Proportional - Uses electrical input signal to control pressure or flow output.
比例—使用电输入信号来控制压力或流量输出。
The electrical signal is amplified electronically, with an increase in signal power occurring at the expense of the input AC power to the amplifier.
电信号被用电子的方法放大，即利用输入放大器的交流电能将信号的功率放大。
Imitating the project of electrical and hydraulic proportional valve, a CAM mechanism is adopted to input and convert the signal of crane arm's radius changing.
系统的控制信号输入方式借鉴电液比例阀方案，采用凸轮杠杆机构，从而利用了凸轮容易实现任意函数关系转换的优点。
The output of the amplifier (electrical current) is controlled by the input signal so with zero input the output current is also zero.
放大器地输出(电流)由输入信号控制，所有零输入信号，电流输出也是零。
The electrical signal may be regulated by a simple potentiometer or one of CEI's input hand controllers "Joy Sticks", or by one of our electronic cards in open or closed-loop operation.
电信号可以通过简单的电位器或一个CEI的输入人工控制器“操纵杆”，或者电卡在开路或者闭环电路运行中进行调节。
